IMPROVEMENT IN MEASURING OIL-CANS.

tion or a central vertical section of my measuring oil-can.

This invention relates to devices for measuring oil and other liquids;and it consists mainly in a measuring-vessel in the form of an invertedcone,.provided with a series of perforations for allowing the escape ofsurplus liquid, and combined with devices for opening or closing any oneof said perforations. It

, also consists in the combination, with said measuring-vessel, of aninclined trough, and external transparent indicator, for the purpose ofshowing when the desired amount of liquid has been supplied to the saidvessel. It also consists in the combination, with the said vessel, ofcertain devices for supplying it with liquid, or cutting off the supplythereof at will. It consists, finally, in the construction, arrangement,and combination of sundry additional devices hereinafter particularlyset forth.

In the annexed drawing, A designates a can or other receptacle forcontaining oil or other liquid.- Said receptacle is provided near itstop with an expansion or bulge, a, in the form of a double cone, whichafi'ords a bearing for a shaft, b, operated by a detachable externalcrank-arm, B, and carrying on the inside of said can or receptacle- A adisk or crankwheel, B. To the inner face of said disk B, is pivotallyattached the upper end of a connecting-rod, O, the lower end of which issim ilarly secured to a plunger or piston rod, 01, that works in pump1). The lower end of said pump is provided with a pipe or tube, E,extending to the bottom of said can or receptacle A, where it isexpanded so as to form a drum or chamber, E, slotted at 6. Instead ofthis construction, the entire tube E may be made larger, and similarlyslotted near the end against a fixed plate, D, attached to the,

upper end of the casing of pump D. Said rod passes through a perforationin said plate, and is braced thereby. Said spring Foperates to close thelower end of tube E; butwhen said rod'F is forcibly depressed againstthe resistance of said spring, the oil or other liquid in can A enterssaid tube E through slot 0, and is drawn up to the pump D by theoperation ofthe devices hereinbei'orc described.

G designates the dischargetube of said pump D, which is bent so as tosupply the said oil or other liquid to a measuring-vessel, H, secured inthe upper part of can A. Said measuring'vessel H is shaped like a hollowinverted cone, provided with two vertical oftsets, H H on opposite sidesthereof, which offsets have vertical external faces each containin g averticalseries'of perforations marked, respectively, 71. or it, forallowing the escape ofliquid exceeding the quantity desired. From thebottom of said measuring-vessel an inclined exit-tube, l, extends to theoutside of can A. J designates a series of horizontal rods provided attheir inner ends with disks or valvesjj, which set against the outsideof perforations h h. Said rods extend through the side of can orreceptacle A, and are provided at. their outer ends with handles J Saidrods are supported by said can, and by a frame, K, rigidly secured tothe inside thereof, through perforations in which they pass, and theyare also provided with collars j and springs J interposed between saidcollars and the inside of can A. Said springs .bear against saidcollars, and operate to hold disks or valvesjj against openings h h.Said openings h h are arranged so that the space in measuring-vessel H,below the level of each one of them, will contain a certai rquantity ofliquid, and this quantity is indicatedby suitable characters on theoutside of can A, near the handle or knob J of the rod J, which opensand closes said perforation. Below measuring-vessel H is arranged aninclined trough or chute, L, which receives the oil or other liquidescaping through apertures h, and conducts the same or a part thereof toa glass indicator or transparent pocket, M, arranged in the side of canor receptacle A. N designates a supply-tube, which connects with theupper part of induction-tube E, and is provided at its upper end with acoupling, so that a flexible tube may be attached thereto. The externalend of said flexible tube connects with the barrel or other reservoirfrom which the liquid is to be originally drawn.

The operation of the devices above described is as follows: Crank-arm Bis turned,

- until, by the action of wheel or disk B and pump D, a considerablequantity of the liquid is supplied to said can or receptacle A. Said canis then disconnected from said barrel, and the rod Jcorresponding to thequantity of liquid to be measured is then drawn out, so as to open oneof the apertures 71. already described. Valve-rod F is then depressed soas to open slot 6. Said rods F and J may be socured in the positionsthus given them by means of any suitable fastening device.

Crank-arm B is again rotated, pumping the liquid up through tube E, andforcing it through bent discharge-tube G into measuring-vessel H. Whenit rises to the level of the aperture h, opened as before described, itoverflows and drops into trough or chute L, which conveys it intotransparent pocket or indicator M. As soon as the operator discovers itspresence there, he stops pumping. When the liquid ceases to flow intosaid indicator, the cock t of exit-tube I may be turned, and therequired quantity drawn off. If preferred, said exit-tube may be leftclosed, retaining the measured liquid until it is required for use.

Offset H is shown provided with a substi tute for rods J and aperturesh. This consists of a vertical guide-plate, H which has a verticalseries of perforations, h that register with perforations h incombination with a slide, 0, which is adapted to be raised or lowered in.the guideway formed between said guide-plateH and offset H so as tocover all the apertures li W, or to leave uncovered any desired numberfrom the top down. The up: per part of said slide may be graduated so asto indicate the quantity of liquid retained in said measuring-vessel inany given position of said slide. slide 0, may all be discarded, andoffset H alone used with its perforations h, and devices for closing thesame, as described.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of tube E, having slot 0 near its lower end, withvalve-rod F, and a spring for holding up said rod, substantially as setforth.

2. The combination of measuring-vessel H, having perforations h withtrough or chute L, and transparent indicator M, substantially as and forthe purpose set forth.

3. The combination of pump D, with devices for operating the same, pipesE, G, and N, measuringvessel H, and can A, substantially as set forth.

In testimony that I claim the above I have I hereunto subscribed my namein the presence of two witnesses.
